Then, they have slowly dried up. Huge ice sheets have come and gone. Along the way, they shaped the land. Mountains are still forming. They often form when two tectonic plates crash together.
Such crashes push bits of land up. North America North America is the third-largest continent. It stretches from the Aleutian Islands to the Isthmus of Panama. The western part of the continent is full of young mountains.
The Rockies are one example. They are North America's largest mountain chain. The East Coast has older mountain chains. North America has many kinds of weather. It has a bigger range of climates than any other continent.
Its Arctic regions are very cold. Other parts are very warm. This is wrong. Mexico is in North America. Greenland is also geographically part of North America, even though Denmark partly controls it.
